ubi: Fix an error pointer dereference in error handling code
commit 5d3805af279c93ef49a64701f35254676d709622 upstream.
If "seen_pebs = init_seen(ubi);" fails then "seen_pebs" is an error pointer
and we try to kfree() it which results in an Oops.
This patch re-arranges the error handling so now it only frees things
which have been allocated successfully.
